Direct Materials, Direct Labor, and Factory Overhead Cost Variance Analysis

Mackinaw Inc. processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 5,600 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	7,300 lb. at $4.80		7,200 lb. at $4.70
Direct labor	1,400 hrs. at $18.20		1,430 hrs. at $18.50
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 1,460 direct
	labor hrs.:
		Variable cost, $4.00	$5,540 variable cost
		Fixed cost, $6.30	$9,198 fixed cost

Each unit requires 0.25 hour of direct labor.
